1320. HIV Care Continuum Outcomes Among Newly Diagnosed PLWH in Washington, DC

BACKGROUND: In 2019, the US Administration announced the Ending the HIV Epidemic plan to decrease new infections. A key component is the Test and Treat plan to diagnose early, treat rapidly and achieve viral suppression (VS) among persons living with HIV (PLWH). We assessed retention in care (RIC), antiretroviral therapy (ART) initiation and VS among newly diagnosed PLWH in Washington, DC. METHODS: We conducted a cross-sectional analysis using data from the DC Cohort, an observational longitudinal cohort of PLWH in care in 14 clinics in DC. We included participants enrolled from 2011 to 2016 whose HIV diagnosis was within 1 year of enrollment and with at least 12 months follow-up. RIC was defined as ≥2 visits or HIV lab results 90 days apart in the first year of follow-up. ART initiation was defined as being prescribed ART, VS was defined as HIV RNA <200 copies/mL, and both these outcomes were assessed at 2 time points: by 3 and 12 months. Adjusted multivariable logistic regression was used to identify clinical and sociodemographic factors associated with RIC, ART initiation and VS. RESULTS: Among the 455 newly diagnosed participants (6% of all enrollees), median age was 33 years (IQR 25, 45), 69% were Black, 79% male, 60% MSM. Median duration of HIV at enrollment was 4.9 months (IQR 2.3, 7.7). Median nadir CD4 count was 346 cells/μL (IQR 224, 494). Of the 455, 38% had a history of AIDS, 92% were RIC, 65% initiated ART by 3 months and 17% had VS by 3 months. There were no differences by sex or race for RIC, ART initiation and VS. An AIDS diagnosis at enrollment was associated with RIC (aOR 2.28; 1.01–5.15), ART initiation by 3 months (aOR 2.41; 1.54–3.76), and VS by 12 months (aOR 1.92; 1.06–3.46). Lower nadir CD4 (aOR 0.89 per 50 cell increase; 0.84–0.94) and younger age (aOR 0.747 per 10-year increase; 0.584–0.995) were associated with ART initiation by 12 months. CONCLUSION: Although the majority of newly diagnosed PLWH were RIC, fewer started ART or achieved VS. With a large proportion of our sample having an AIDS diagnosis at enrollment, we illustrate the ongoing challenge of late HIV diagnosis in DC. Those with AIDS at diagnosis were more likely to initiate ART within the first 3 months. As same-day ART initiation is scaled up in DC, future research can evaluate if all PLWH, regardless of AIDS status, will achieve this milestone earlier.
